| Outline of Final Research Achievements |
I investigated the factors that contributed to the persistence of production of late-maturing paddy rice varieties by using administrative data, statistical data, and interviews, using "Akebono" and "Asahi" in Okayama City and "Hatsushimo" in Gifu Prefecture as examples. The results showed that the following factors influenced the persistence of late-season rice varieties: the water use conditions of the reclaimed land required late-season rice varieties, they required only a small amount of fertilizer, thus reducing costs, and they were suitable for labor-saving dry-field direct seeding cultivation. The study suggests the possibility of selecting varieties for labor-saving and increasing leisure time, rather than aiming to increase productivity, and will provide material for reexamining the direction of agricultural innovation in an era of declining population.

農業イノベーションの発展経路についての見直しと、今後の方向性の再検討を迫る材料となることが考えられる。農耕史研究では、生産力の発展を主軸として社会経済変化を捉えようとする「農耕中心史観」を相対化するような成果が存在し、余暇時間拡大、あるいは余暇そのものとしての農耕（play farming）発展という見方も登場している。また、農村地域における高齢化と人口減少、後継者や移住者における生業の複合化といった現状は、生産力増強より省力化や余暇時間拡大のためのイノベーションをより重視することになると考えられる。こうした方向での技術変化論の研究は未だ貴重であり、本課題の成果が重要な貢献をなすと考える。
